SPECIFICATION forming part of Letters I Patent No. 379,114. dated March 6, 1888.

Serial No. 236.133. (No model.)

To all whom it may concern.-

Beit known that we, ANTHONY lsKE and ALBERT IsKE, citizens of the United States,

residing at Lancaster, in the county of Lancaster and State of Pennsylvania, have invented certain new and useful Improvements in Bells", and we do hereby declare the following to be a, full, clear, andexact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to bells operated by clock-work, and has for its object to provide a cheap and reliable bell of this sort, suitable for any use where a continuous alarm is required, and wound by a pull'on a string in any direction, the release of the string sufticing to set the mechanism going. To effect this we employ an ordinary bell and astationary shaft, in combination with clock-work mechanism free to rotate about s'aid shaft, a winding-pulley or circular series of pins and mainspring for driving said clock-Work, and a hammer operated by said clockwork to strike said bell. These devices will be hereinafter more particularly set forth and claimed.

In the accompanying drawings, Figure l represents a side elevation of the bell and op erating mechanism, a part of the bell being brok en away. Fig. 2 represents a vertical section through the same on the central line x of Fig. 1. Fig. 3 represents a horizontal section through the same on the line y y of Figs. l and 2. Fig. 4. represents a detail view of the `base and the shaft fixed thereto, with the ratchet-wheel on the latter. Fig. 5 represents a detail view of the pins for the windingcord, the bottom plate,and the mechanism mounted thereon. Fig. 6 represents a detail view of the fixed ratchet-wheel, the spring-pressed pawl engaging therewith, and the gear-wheel which carries said pawl. Fig. 7 represents a detail view of the pulley sometimes substituted for the winding-pins.

A designates an ordinary supporting bracket, to which a base, B, preferably dish shaped and of cast metal, is secured by a screwthreaded stud, b, and a nut, b', or by bolts passed through holes b2 in said base. A fixed vertical shaft, C, arises from the center of said l base, having a ratchet-wheel, C, immovable thereon. This ratchet-wheel is engaged by a pawl, D, held in Contact therewith by a spring, d, said spring and pawl being attached to the side of a gear-wheel, E, which is freely mounted on said shaft C. A coiled mainspring, F, is attached at its inner end to said shaft C and has its outer end attached to one of three pillars, G, which connect the two platesH I of the clock-work mechanism. The lower plate, H, hasa circular series of rigid pins, z, extending down from its under side and constituting in effect a winding-pulley. Acomplete grooved pulley, L, as shown in Fig. 7, is sometimes substituted for them. Athird plate, J, heavier and stronger than Hand' I, is mounted on said pillars Grigidly above plate I, and affords abase 'for gong-bell K, which is attached to said plate J by a screw, k, that passes through a central hole in said bell and enters a screw-tapped recess in a boss, j, of the last-named plate. Small vertical shafts M N are journaled in platesH I. The shaft M carries a lantern-wheel, O, meshingwith wheel E; also an escapement-wheel, P, engaged by pallets n n on shaft N. The latter shaft carries in addition a hammer, Q, which strikes the bell K. A cord, R, is attached to the periphery of the winding-pulley L, Fig. 7, or to one of the pins z, as stated, passed partly around the pulley or series of pins, then out through a guideway, S, in the side of the base B. This guideway does not allow the cord to pull away from that point in the'circumference of said pull of the cord on said pulley or series of pins will be always the same, no matter from what side of the alarm the outer end of the cord be seized and drawn.

The operation is as follows: The cord R,be ing p ulled,rotates the winding-pulley L or the series of pins z. through part of a circle, said pulley or pins of course carrying with it or them the plates I-I I J, the bell K, the pillars G, the shafts M N, the wheels O P, the pallets n n, and the hammer Q. The outer end of spring F is carried around also by the pillar G,to which it is attached, thus winding said spring. At the same time the wheel E turns freely backward, being engaged by pinion or base, and by consequence the direction of thev IOO lantern-wheel O, but without rotating the latter, the pawl D riding freely backward over the ratchet-wheel C. Vhen the cord R is released, the spring F turns the plates H I and the parts attached thereto in the opposite direction, the pawl D and Xed ratchet-wheel C hold the wheel E motionless, and the engagement of the lantern-wheel O with said wheel E gives to said wheel and its shaft M a rotary axial motion of their own beside the revolution about the fixed shaft G which they have with the other` parts of the alarm mechanism, turning as a whole on said shaft.

The bell and its operating mechanism,as describcd,niay be used for any purpose to which a bell operated by a rapid series of strokes is applicable The device is available asa burg lar or fire alarm without any change whatever. Its simplicity and durability are evident.

Having thus described our invention, what we claim as new, and desire to secure by Letters Patent, is-

l. A winding pulley or plate and its winding-cord,in combination with a shaft, @,around which said pulley turns, a coiled spring, F, attached to said shaft at one end7 a series of pillars, G, supported on said pulley or plate and having the other end of said spring attached to one of them, the plates I.J,supported on said pillars. the gong K, mounted on plate J, the shafts M and N, journaled in said pulley and plate I and carried around thereby, gear-wheels carried by these shafts, a wheel, E, meshing with one of these gear-wheels and loose on shaft C, a spring-pressed pawl carried by said wheel E, a ratchet-wheel fixed on said shaft and engaging said ratchet to allow the rotation of said wheel E in one direction only, the escapement-wheel P on shaft M, the pallets n a on shalt N, engaging therewith, and the hammer Q, also carried by shaft N, all arranged and operati ng substantially as set forth.

2. A stationary shaft and a gear-wheel, E, thereon, in combination with a pulley turning on said shaft, a frame mounted on saidA pulley and turning therewith, shafts M N, ljournaled in said frame and pulley, a coiled spring attached at one end to said shaft and at the other to said frame, a bell, hammer, and pal lets attached to shaft N, an escapement-wheel and gear-wheel on shaftl M, the latter wheel meshing with wheel E, a gong carried by said frame, and a cord passing around said pulley for winding, substantially as set forth.

In testimony whereof we affix our si gnatu rcs in presence of two witnesses.
